Most growers will roll their beans shortly after seeding in order to prevent stones from entering the combine at harvest time and to make harvesting easier and quicker. On dry springs when soil conditions could lead to soil drifting a grower can wait and roll there beans after they are up and are at the first trifoliate stage..
When rolling after emergence
- Do not roll at the Hook Stage- This is when beans are first emerging.
- Do not roll in the morning wait until air temperature are around 25C before you start to roll to avoid damage to the plants.
- Check for damaged plants to ensure plants are not breaking off.
- If damage is too sever wait for a warmer day.
The attached video outlines some of the reminders about rolling beans.
